Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed March 27, 1905. Serial No. 252,329.

To all whom it may concern.-

Be it known that I, WILLIAM SINCLAIR, of San Antonio, in the county of Bexar and State of Texas, have invented certain new and useful Improvements in Acetylene-Generators; and I hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, which form part of this specification.

This invention is an improved acetylenegas-generating apparatus, and it has particular reference to the charging device whereby the carbid is introduced into the generatingchamber.

The invention in particular is an improvement upon the apparatus disclosed in my Patent No. 784,811, dated March 1 1905; and the particular object of the present invention is to improve the construction of the carbidcharge disclosed in such application.

The invention consists in the novel construction and combination of parts hereinafter described and claimed, and illustrated in the accompanying drawings, in which- Figure 1 is a sectional elevation of a complete generating apparatus, showing the carbid-charger in full lines in the generatingchamber in position for generating gas. Fig. 2 is an enlarged top view of the charger detached. Fig. 3 is a longitudinal section through the charger.

The apparatus comprises a gasometer having a bell A, which telescopes into a water seal 6 in the lower part of the tank B, which is closed at its upper end within the bell by a conical head 6', that forms the floor of the gas-chamber within the bell. The bell may be guided in its movements by rods attached to the upper end of tank B and passing through guides at on the sides of the bell, as shown. Rods C may also be braced by a cross-tie O, as shown. At the lower part of the tank is the generating-chamber D, which is kept almost or quite full of water and communicates with the bell by a pipe or passage cZ and said chamber communicates at bottom through an opening (Z with the lower end of a water-leg .nto the generating-chamber through the leg E and opening cl, and said charger is preferably constructed of a metal cylinder or holder Gr, closed at one end and open at the other. This open end of the cylinder is, however, closable by a conoidal metal cover H, which is attached to one end of a rod it, that is bent over the side of the cap and extends alongside the holder and is guided in perforated lugs g and attached to the side of the holder. A coiled spring is interposed between the foremost lug g and a collar or pin 71 on rod it, so as to normally hold the cover H tightly closed; but by forcibly pulling the cover outward against the tension of spring 71 it can be freed from the holder and turned to one side, so that the holder can be filled or cleaned readily. The holder is connected at its rear end to the lower end of a handle-rod J, the lower end of which is preferably bent upwardly at a slight angle and is pivotally connected to the holder by a bolt transfixing ears g on the closed end of the holder, as shown. The rod J is long enough to allow the holder to be inserted through leg E into the generating-chamber, and then by depressing the handle-rod the holder can be tilted upwardly in the generating-chamber, as shown in Fig. 1, whereupon water will en ter the holder through apertures H in the cover H, and the generated gases escaping therefrom into chamber D pass upward through passage d into the gas-bell A. The extremity J of rod J may project beyond the pivot j sufficiently to prevent the holder being tilted to an entirely upright position. The rod it may be arranged at the side of the holder, and the latter may be provided with a roller G on thefforward end and under side to facilitate its entry into and removal from the generating-chamber.

Operation: The gasometer being in operative condition and pipe F properly connected to the gas-consuming devices, chamber D and leg E are filled with water. The operator then opens holder E by turning its cover H to one side, as indicated in dotted lines, Fig. 2, and places therein a proper amount of carbid to generate the desired quantity of gas, which should be about the amount bell A will contain. Then the operator closes cover H,

which is held closed by spring h, and then lowers the holder, mouth downward, into leg E, and when its lower end or mouth touches the bottom of the leg it slides inward through opening 0Z into the bottom of chamber D and is tilted upwardly on its wheel G, as shown there is no danger of waste or loss, and as the Water enters the holder in small quantities through the same openings that the gas leaves it there is no dangerous sudden generation of gas, but a steady continuous generation until the carbid is exhausted. All the slime from the carbid remains in the holder and is removed therewith by simply pulling it out by rod F, and the holder can be easily cleaned after turning the cover H to one side.

This apparatus is simple and efficient. There are no so-called automatic regulators,cocks, valves, or levers to look after. The holder can be left in the generating-chamber until the descent of the bell shows the supply of gas is exhausted. No water is run off, and the operator by simply keeping the leg properly full of water insures a proper and suflicient volume of water in the generating-chamber, and no gas is wasted. Any gas absorbed by the water in the generating-chamber remains in said chamber until it escapes into the bell, and the gas passes through a considerable quantity of water in the generating-chamber and is cooled and purified thereby. The device can be operated by inexperienced persons with perfect safety and without fouling the apparatus with waste carbid.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

lfln combination, a gasometer having a Water-containing generating-chamber and a water-containing leg communicating at bottom with such generating-chamber; with a carbid-charging vessel having a mouth, a cover for closing said mouth, a spring for holding said cover closed while the charger is in use, and means whereby the vessel may be introduced mouth downward through the leg and moved into the generating-chamber, substantially as and for the purpose described.

2, In combination, a gasometer having an interior water-containing generating-chamber and an exterior water-containing leg communicating at bottom with such generating-chamher; with a carbid-charging vessel having a mouth, a conoidal-shaped cover for closing said mouth, and a spring for holding said cover closed during the operation of the charger; with means whereby said charging vessel may be introduced mouth downward through the leg'and into the generating-chamber, substantially as and for the purpose described.

3. In combination with a gasometer having a water-containing generating-chamber, and a water-containing leg communicating at bottom with such generating-chamber, of a carbid-charger comprising a holder open at one end, a cover closing the mouth of said holder, a rod attached to said cover and bent over and alongside the holder, guides for said rod on the holder, a spring for holding the cover closed, and means for introducing the holder mouth downward through the leg and into the generating-chamber, substantially as described.

4. A carbid-charging device for acetylenegas generators, comprising a holder open at one end, a cover for closing the open end of said holder, a rod movable in guides on the holder having its forward end connected to the cover, a spring on said rod for holding the cover normally closed, perforations in the cover for admitting water into the holder, and

a handle-rod having its lower end pivotally V connected to the holder, all substantially as and for the purpose described.

5. The herein-described carbid -charging device for acetylene-gas generators, comprising a holder open at one end, a conoidal shaped cover for closing the open end of said holder, a rod movable in guides on the side of the holder, and having its forward end bent over and connected to the cover, a spring on said rod for holding the cover normally closed, perforations in the cover for admitting air into the holder, and a handle-rod having its lower end bent upwardly and pivotally connected to the rear or closed end of said holder, all substantially as and for. the purpose described. 1

In testimony that I claim the foregoing as my own I aflix my signature in presence of two witnesses. WILLIAM SINCLAIR. In presence of (J. M. STONE, JHs. ANDRESNEN.
